On Tuesday the Global Commission on the Economy and Climate launched its report, Better Growth, Better Climate, in which it makes the bold-sounding pronouncement that major steps can be taken to address climate change that cost nothing. Over the next 15 years we will spend some $90 trillion in infrastructure investment. "Our argument is that it would be smart to invest the $90 trillion in a good way," said Jeremy Oppenheim on APM Marketplace on Tuesday.
In a way, we have always known this. The question has always been, can you measure and quantify the risks and the known harms from climate change? Even if there remain uncertainties, it is increasingly incredible to deny that the balance of climate risks and mitigation costs tilts in favor of deep emissions reductions. So why do we still debate it? Why does it still seem as though reducing emissions is costly?
The answer goes back to my previous post, in which we do not explicitly grapple with the "losers" from climate policy, coal-related industries and states, petroleum industries, states, and countries, and all of the related industries. There is a lot of capital, physical, human, and social wrapped up in a lot of industries and places, and they may not be able to do much other than what they're doing, which is to continue to service a greenhouse gas-intensive economy. In theory, we could buy them out with the cost savings of avoiding all those climate harms. But in practice, we just don't have the money.
